Heat Transfer through a Long Fin
The rate of heat transfer from a fin is directly proportional to:
Let us say there are two rods having same dimensions, one made of brass (k = 85W/m K) and the other of copper (k = 375W/m K), having one of their ends inserted into a furnace. At a section 10.5 cm away from the furnace, the temperature of brass rod is 120 degree Celsius. Find the distance at which the same temperature would be reached in the copper rod? Both ends are exposed to the same environment.
The fin parameters are as follows: Dia. of the fin 2 cm. thermal conductivity = 200 W/mK, convective heat transfer coefficient =12 W/m-K base temperature of the fin = 500 °C, Air temperature = 50 °C. The rate of heat transfer from the fin is
Find the heat transfer rate from a hot surface for 6 fins of 10 cm length? The base temperature of the fin is maintained at 200 degree Celsius and the film is exposed to a convection environment at 15 degree Celsius with convective coefficient 25W/square m K. Each fin has cross-sectional area 2.5 square centimeter and is made of a material having thermal conductivity 250W/m K.
What is one of the assumptions made in the analysis of fins?
